HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 271,118, dated January23, 1883.

Application filed September 11, 1882. (No model.)

To all whom it may concern:

Be it known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county ofMiddlesex and State ot'Massachusetts, havein vented acertain new anduseful Improvement in Heel-Nailing Machines, of which the following is afull, clear and exact description, reference being had to theaccompanying drawings, forming a part of this specification, inexplaining its nature, in which- Figure l is a plan view of atemplet-plate, templet-table, and nailholder. Fig.2 is a plan view ofthe same parts illustrating a modification. Fig. 3 is a vertical sectionupon theline m w of Fig. 1, showingadditionally the drivers and heel inposition. Fig. 4 is a view representing another form of' carrying out myinvention-with effect.

The invention relates especially to the nailholdcr, and -it'is animprovement upon that described in Letters Patent Nos. 252,215 and259,687, for heel-naili n g m achines, both granted toHenryA.Hendersomassignor. In said pat- .ents a perforated nail-holderhaving a perforated sliding plate or bottom for closing and opening theholes in the holder is shown and described, and I desire to do awaywiththe use of the perforated sliding plateor bottom. To accomplish this Imake the nail-holder A in two or more parts, a at. These parts areadapted to be moved on the templet-plate, or a continuation thereof,upon a curved or straight line from the place Where the nails areinserted into the nail-receiving holes of the nail-holder to the pointwhere they discharge the nails into the templet; and I have representedin Figs. 1 and 3 the parts a an adapted to be moved upon their centers aupon the templet B. Preferably each of these parts is provided with thesegmental gear a at its end, which mesh with each other, so that themovement of one section of the nail-holdershall cause the movementof'the other; and in use the nail-holder will have the position shown indotted lines in Fig. 1 in loading, and having been loaded, the operator,by means of the handie a, moves both parts simultaneously to theposition on the templet-plate shown in full lines, thereby causing theholes in the nailholder to register with the holes in the templet andthe nails to discharge.

Any suitable stop-lug or projection upon the templet-plate may be usedfor causing the movement of the parts to stop when the holes are broughtinto line with the templet-holes. In lieu of this movement, I may useguidingslots 0, (shown in Fig. 2,) into which pins or projections 0 uponthe under surface of the holders shall project. In this event the partsof the nail-holder would be moved from the place where the nails wereloaded to a position to cause the holes to register with the holes inthe templet-plate upon a line or substantially upon a line with theguiding-slots. Of course, in lieu of the slots, there may be projectionsupon the templet-plate for guiding the parts of the nail-holder intoposition, so that the holes therein shall register with thetem-pletholes, in which case the parts of the nail-holder may be loadedand moved on the templetplate until the guiding-projections are reached,when by these .means they are brought into position over the templet toregister. This construction is represented in Fig. 4. These guides mayproject into recesses in the nailholder or bear upon the ends of eachpart.

It is obvious, on account of the location'ot the holes in the templet inrelation to each other, that a nailholder cannot be in one piece and bemoved in one direction upon the templet, because of the liability of theholder unloading some of its nails into the wrong holes in the templet,as there are at least two holes which are likely to be upon the sameline of movement, and of course the nail-holder would discharge thenails into the first holes that registered. Therefore it is essentialthat it be divided in order that the movements shall be away from eachhole, instead of upon a line with two or more of them and while I haveshown the holder divided into two parts of course it may be divided intomore, if desired, without departing from the spirit of the invention.

For ease and quickness of operation it is desirable that the movement ofone part cause a like movement of the other; and while I haverepresented one way of obtaining this result I do not confinemyself tothat way, but include any mechanical equivalent for the mechanism shownand described.

It will be observed that this construction is cheap and that by it noauxiliary plate to cover and uncover the holes in the nail-holder isnecessary. Having thus fully described my invention, I claim and desireto secure by Letters Patent of the United Statesi 1. In aheel-nailingmachine, in combination with the templet and templet-plate, anail-holder in two or more parts, which are adapted to be moved upon thetemplet-plate and brought together into position to cause the holes ofthe nail-holder to register with the templet holes, all substantially asand for the purposes described.

2. In combination with atemplet, a sectional I 5 nail-holder andconnecting mechanism Whereby both sections are simultaneously movedforward, all substantially as and for the purposes described.

3. The combination of the templet-plate, the 20 nail-holder in two ormore parts, and suitable guides for centering the parts of thenail-holder upon the templet, all substantially as and for the purposesdescribed. I
